What important observation did Edwin Hubble make about the movement of galaxies?
In the late 1920s, the astronomer Edwin Hubble discovered that most of the galaxies he observed were moving away from Earth.
Can you give a hypothesis for a balloon powered car?
If the car is lighter, Then the balloon powered car will go further.
What are two things in nature that are periodic?
The rotation of the galaxies, and the rotation of the electron.
Passive prostheses are?
Self powered
What two items that are solar powered?
well if u have solar panels that means that your houses electricity is then solar powered (or generated) a lizard as the need the sun to get there energy glow in the dark things can be solar powered as the need the suns light to the glow
What are active galaxies powered by?
A central, supermassive black hole.
Who thought of galaxies?
astronomers did
Collisions between galaxies is thought to?
Have no real effect on the merging "colliding" galaxies
How are black holes involved in understanding active galaxies?
It is difficult to ask black holes about how they are involved in active galaxy research because they cannot talk, this makes them only peripherally involved in understanding active galaxies
Which of the galaxies is shaped like a sphere or an egg?
you would of thought
What are the release dates for Astronomy Observations and Theories - 2005 Active Galaxies 1-14?
Astronomy Observations and Theories - 2005 Active Galaxies 1-14 was released on: USA: 21 June 2006
What is tough to be at the very center of all galaxies?
Perhaps you mean "thought to be"? - It is believed that all, or most, galaxies have a supermassive black hole at their center.
How many galaxies are irregular?
Irregular galaxies are thought to represent about 25% of all the galaxies. That puts the total at around 25 billion - depending on the source for the total amount (100 -> 300 billion)
How are scientist able to identify the different types of galaxies?
The scientists are able to identify the different types of galaxies by high powered telescopes and by examining the pictures sent by various satellites orbiting the universe.
What is a young galaxy with a giant black hole in the center called?
quasar
How is know that active galaxies have small core regions?
It is known that active galaxies have small core regions because we can see them in images! These small regions known as uassars emit perful amounts of both radio waves and gamma rays...
What are distant galaxies with black holes in their centers called?
There have been some suggestions that the objects called quasars might be extremely active galaxies with unusually supermassive black holes at their centers at such great distance from us that it is not possible for telescopes to resolve their galactic structure, making them just look like very bright stars (quasi-stellar objects). However this has not been verified.If these suggestions are correct, these extremely active galaxies must be so distant that the light we are seeing from them must have been emitted only a short time after the big bang began, in the initial cycle of star formation, which would make them the earliest galaxies formed and likely very young galaxies. However if they are this young these extremely active galaxies might have galactic structures so different from the galaxies we are familiar with that even if our telescopes could resolve them, we might not recognize them as galaxies.
